Hi,
I've just installed CentOS on my new machine and I'm wondering about a thing: the refresh rate is set rather low (it looks like 50Hz), whereas the monitor can at least support 75Hz in 1152x864 resolution (which is the resolution I set the monitor at).
Now... for some reason CentOS decided to use the generic VESA video driver, so perhaps this is the issue, and perhaps a better (i.e. more specific) video driver would give me the additional refresh rates, but then, from Gnome's -> System Settings -> Display menu, I do not see any choices for the refresh rate at all. It does, however, make change to /etc/X11/xorg.conf.
The motherboard is an ASRock K7S41GX, and it seems the video adapter that is used is a bridged (North Bridge?) SiS 741GX one. Unfortunately the CD-ROM that came with the machine only has W*nd*ws drivers for this chip set. :(
Does anyone know if I can somehow force the generic VESA driver to run at 75Hz, or does anyone know where I can find the proper video driver (I do not see it listed in the list of available video drivers)?
Meanwhile, I'll take a look myself on Google as well, but I hope someone can give me some quick pointers...
Cheers! Olafo
